Leaves have massively yellowed overnight

My room has several strains at various stages of flowering. Last night I moved a couple of new plants into the room and cropped a couple that were 100 days in the room (supposed to be a 55-60 day indica Pineapple Chunk). I am not the biggest fan of long whispy buds (maybe it's only me).
On the other hand I have the stinkiest La Blanca (freebie) that has been going gang-busters. I just read it doesn't need too many nutes. It is been in there since 10/17 with several weeks to go (although all trichs are cloudy already). That plant yellowed significantly overnight (though I haven't fed in 3 nights). The plants that yellowed the most are King Kong, I mean virtually the entire plant has yellowed and it has a month left (at least). The lights went off this am and all looked fine...When I just opened the door it was a jungle of yellow....Any help or advice would be WAY appreciated...

Okay now I have smoked a bowl I have calmed down a bit. I think I need to add I am using FF nutes and micro nutes. I read a sticky on diagnosing plant problems. Is it possible for a plant to yellow overnight because of a N deficiency? How about cal/mag? Should I add a little Grow Big or try some epsom salt?

Give that one a hit with veg nutes then go back to flowering nutes.

Did you follow the Fox Farms feeding schedule and give them grow big during week 3 and 4?

They got GB while vegging, 1 time during the 3 Open Sesame feedings & 2 times during Beastie Bloom feedings. It's been a couple/few weeks since they got any GB. I am going to give then a tsp of GB tonight....I haven't given any mollases yet, that might help uptake some more nutes? My PH might be a little high too...6.9-7.0?

Have you been using sludgehammer on schedule? The stuff is amazing.

LOL...Slugehammer...I spent the last 5 minutes googling it. All I got was waste water treatment info..LOL I typed in "Sledgehammer" and got the gist...I haven't really flushed any of them. I have this Grotek stuff called "The Final Flush"...Looks like it is just ascorbic acid & citric acid (vitamin C).
My feedings go like this....When I feed a put a smallish amount of PHed water on the plant, then I add nutes just until I get a trickle out of the bottoms of the pots. Watering on the other hand I pretty much soak them until more water comes out of the bottom.
I am using Roots Organic soil which drains like crazy. Regardless of how much water I use, they are nearly bone dry after 3 days, max. I don't know how many grows I have under my belt now (not too many) maybe 4 or 5? My experience is more vicarious through reading your guy's grow journals. If it wasn't for this forum (and others like it) my head would be even further up my ass and would be really floundering...As it is though, I am growing some DANK bud, head up my ass or not. I am just starting to get patient enough to let plants finish (more or less).

too fucking high dude what ya tryna do fuck up your hard work. 5.3-6.3 no higher than 6.4 man flush your shit with some ph balanced water to get your ro level right from your soil
